Now when junior complains that one of the evil neighborhood kids has stolen his favorite toy, hand him this Lil' CSI kit, complete with UV light, and get him dusting for prints.

There's even an ID card and ink pad so anyone that enters said playroom can get their prints on file, in case any funny business should happen later, and some evidence sacks to bag up incriminating fibers. What every kid needs is their own high-security, civil-rights-violating border crossing station in his room. I had my prints lifted off a water bottle, so this thing works. It's $16 and available this fall. [Toy Fair 2009]
